The EU is committed to preserving the nuclear deal with Iran and helping the nation dodge US economic sanctions, and will not bend to any ultimatums, top European diplomats say. Earlier, Tehran suspended some of its commitments.

On Wednesday, Tehran announced it will halt disposal of excessive heavy water and uranium, which is one of the key terms of the 2015 nuclear agreement (known as the JCPOA). Unless European signatories deliver on their promises to Iran, it may enact a further rollback in 60 days.

EU members pledged to create a special financial mechanism which would allow business to be done in Iran without being on the radar of the US, which threatens anyone dealing with the country with economic sanctions.

Top EU diplomats said on Thursday they remain committed to the deal but will not bend to any ultimatums.

“We strongly urge Iran to continue to implement its commitments under the JCPoA in full as it has done until now and to refrain from any escalatory steps,” the officials said in a statement.

Iran for its part stressed that it wants to fix the JCPOA and not abandon it.

“Our goal is to strengthen the JCPOA and bring it back on track,” Behrouz Kamalvandi, spokesman of the Atomic Energy Organization, said the same day.

Earlier, Tehran clarified that its decision to partially suspend compliance with the JCPOA was in response to the US’ withdrawal and the failure by European signatories to alleviate the damage done by American sanctions.

The deal offered Iran the lifting of sanctions in exchange for placing restrictions on its nuclear industry. Lucrative business deals with European and American companies were expected to follow, boosting Iran’s economy and building trust with the West.
